T 0 all wwm z't may] concern:

Be it known that I, FRANZ A. FULLER, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Bag-Fasteners, of which the following is a specification, reference being had therein to the accompanying drawings, which form a part thereof.

My invention relates to bag fasteners and more particularly to a type thereof vapplicable to bag frames having pivotally connected frame members and embodying therein a lift latch adapted to lock said frame members when closed.

'ln bag frames of the character above referred to, two hinged frame members :formed of channeled metal stock are used, and the bag body is secured to the frame by having the edges thereof inserted in the channel of said members. These edges may be held in the frame members in any desired manner or by any desired or wellknown means.

rl`he manner of connecting the bag body to the frame members, makes it highly desirable to keep the channel of said frame members free of obstructions, so as to avoid the necessity for cutting the edges Vof the bag body or its support to clear such ob.- structions. This iitting not only causes additional labor in assembling the bag structure but additional tools and appliances are necessitated there-by.

ln a 'bag fastener made in accordance with my invention, the controlling spring for the lift member or knob is so constructed, and so mounted in the frame member as to be substantially flat, parallel with and in close juxtaposition to the top of the frame member, while it is especially adapted for use in connection with a ba-g frame member substantially rectangular in cross-section, it may, with slight modification be adapted to -a frame of any configuration providing that suiiicient lclearance is afforded adjacent the top of the frame to :accommodate the spring and its tensioning. means.

In the form of the -inventionshow-n, the tensioning means consists of a keeper -adaptu ed to operatively 4engage an angularly 'projected end of the spring, said keeper'being iirmly attached feto the frame member by riveting, soldering, brazing or otherwise. ,llo bring the' Wholefsrfinsf mechanism finto .sired tension in the spring, but preventing axial displacement of the spring thus permitting the connection of the spring to the lift knob by means of a sliding tit between the spring and the socket in the spring lug.

"That portion of the keeper bearing upon the top frame adjacent its point of connection therewith, is preferably stiffened, and one edge of the keeper adjacent the recess therein is cut away so as to avoid interference with the free action of the spring. The construction and manner of vattachment of the spring with relation to the frame is such as to bring substantially all portions thereof within the clearance necessary for the free movement of the lng of the lift member or knob; and the application of the keeper to the frame member may not only be simply accomplished, but will result in the tensioning of the spring so that the diiliculties of mounting the spring withre- Alation to the lift member or knob will be reduced to a minimum. Furthermore, the mounting of the lift member' or knob and its controlling spring will require no moditi cation of the frame member itself and thus will not in any way interfere withthe artistic lines of said member.

The invention consists primarily in a bag fastener embodying therein a channeled member having an opening therein adapted to receive the springing of the lift member ,or knob, a lift member ,or knob having a spring lug thereon adapted to be projected through Said opening and .within Said channeled member, a .spring having one straight section operatively connected with the lug oi said lift member or knob and another straight section terminating in a projection extending` angularly thereto, a keeper enspring section and a nose or catch adapted -to be mounted upon a fmember movable with `gti-ging the turned end of said last named i or knob; and inlsuch othernovel Vfeatures of construction'and combination of parts as Eare :hereinafter ,set forth and described -and iinore particularly pointed outin the ,el aims gliereteaepeade@ vini y form of spring,

Like letters refer to like parts throughout the several views.

In the embodiment of my invention shown Y in the drawings, the channeled member supfst porting the lift member or knob is shown as consisting of one of a pair of hinged framemembers a-b. rI`hese members each consist of a main body having hinge members a a2 b2 respectively. The said hinge members are pivotally connected at'c and o.

One of these frame members as a is provided substantially centrally thereof with an opening d adapted to permit the passage of the spring lug of a lift member or knob therethrough, which lug is exposed within the channel of the frame. The lift knob e is of the usual and well-known construction being provided with a pendant rim e adapted to project across the other frame member b and operatively engage the nose or catch 7 carried thereby. This lift member or knob is provided with an integral lug g to which the controlling spring is adapted to be operatively connected in any desired manner. Preferably, however, this lug is provided with an angular socket adapted to receive a spring, the end of which is so formed as to have a sliding fit therein.

In the practice of my invention, I employ a controlling spring for the lift member or knob composed of two sections, one of which, as L, is operatively connected with the spring lug g and the other of which as z has its end z" turned at an angle thereto so that said section may be subjected to a twisting action to develop a torsional stressV thereupon, which stress is transmitted to the'other section it. The section 7L is preferably connected to the spring socket g by having one end thereof as h angularly formed so as to have a sliding fit within the socket in said lng. The sections L-z' are formed from a single strand of spring wire bent upon itself so as to bring said sections into a substantially parallel relation, the section z' being of a length to bring the projection z" thereof beyond the end of the section L and at one side of the luor g.

To tension the said spring, the projection Vz" thereof is forced toward the top of the `member, a and held in this position by means of a keeper, one portion of which is adapted to engage said end, and the other portion of which is adapted to be permanently connectedwvith or attached to thertop of the said member a. Y'I` his keeper preferably is in the form of a small bracket having one arm j thereof provided with reinforced stiffening ribs j and the other arm thereof 76 provided with a recess or seat 7c adapted to receive the projection fi. Said bracket is adapted to engage the top of the said frame member so as to confine the projection z" and prevent its movement toward the lug g. To facilitate the application of the keeper to the spring and to theframemember, I cut away a portion thereof as at k2 and allow clearance for the spring section z' adjacent the projection c" thereof. The ribs y"k terminate adjacent the transverse recess k. The keeper is mounted in relation to the frame member a, preferably by means of a rivet Z passing through the arm j and the top of said frame, but if desired'this keeper Y may be permanently secured in position in any other desired manner. Y

The arm c of said keeper, before it is assembled in the frame, is flat and projected at an angle as indicated in dotted lines in Fig. 4, the recessv 7c being formed therein by means of a tool forcing said arm 7c to place after the arm j has been riveted to the frame. Downward pressure upon the arm 7c' will force said arm and-the projection Z, thus exerting a torsional stress upon 'the spring Section z' and transmitting such stress together with a direct stress uponthe section h with a resultant normal tendency to said spring to tilt the lift member or knob toward the frame member toa position where it will automatically engage the nose or catch The elongation ofthe section i will also permit thatside sway thereof incidental to the actuatiton of the lift member or knob which is dueto the eccentricity of the lug gg Y i f The portion of the arm l@ adjacent the cut away portion 7c will, when the bracket is properly positioned, be forced against the top of the frame member c. Hence the section z' will not interfere with-the 'operation by which the final form is given to said bracket.`

The lug g, the controlling spring coperating therewith, and the bracket tensioning said spring. all lie in close juxtaposition to the top of the channel member carrying the same, and all of them project so slightly into said channel as not to interfere in any way with the covering material for the frame or the edges of the bag body when they are inserted in the channel of, and secured to, said frame. Y Y

The form of said Spring and the construction by which it is attached to the frame member a, are such as to preclude any possibihty of its disarrangement. This condit1on avoids possibilityY of the accidental needing@ opening of the bag through the breakage of the spring.

A bag fastenermade in accordance with my invention is not only inexpensive to produce, but may be quickly and conveniently assembled.

it is not my intention to limit the invention to the precise details of construction shovvn in the drawings, it being apparent that such may be varied Without departing from the spirit and scope of the invention.

Having described the invention, what I claim as new and desire to have protected by Letters Patent is:
